The Irish Famine

1845–1852 CE — British Isles, Ireland

Today: Ireland

A water mould arrived from the Americas and destroyed Ireland's potato crop, the food of a third of the population, who ate it because it yielded more calories per acre than anything else on the small plots they had been left. Roughly a million died and a million emigrated. Throughout, Ireland exported food to Britain under armed guard — the crops were the landlords', and the government's commitment to letting markets work meant relief was limited and grudging. A crop failure became a catastrophe because of who owned the land and what the state believed about intervening.

Worth knowing: Ireland's population has never recovered. It stood at roughly 8 million in 1841 and is under 7 million today across the whole island, nearly two centuries later — the only country in Europe with fewer people now than in the 1840s.

Pattern: Environmental & resource stress — An environmental shift (drought, cooling) strains food and water systems, amplifying every other tension at once.
